I have one question...why in the hell do you want a "giant" phone? What ever happened to the days of creating smaller devices that didn't take up a whole pocket. The whole point of a cell phone is exactly that, a cellular phone. I like apps and games on my phone just as much as the next person, but there comes a time when we need to sit down and realize we don't need bigger screens. We have devices made with bigger screens you can purchase for those activities. The iPhone screen is currently as big as it should get in my opinion. If everyone and their mother keeps asking for a "bigger screen" soon enough we might as well walk around with iPads strapped to our hips, then what happens when those screens aren't big enough? We carry around 15" phones? The whole point I'm attempting to make we have to stop the "more" mentality. As has been pointed out in this thread, there are devices made for specific purposes if you wish to have that. I don't need a phone I can have multiple windows open on. I don't need a phone that comes with a stylus (pretty sure that's a step backwards in time to the PDA days). I mean does no one remember the days of bag phones? Sure we can create lighter devices now, but we're back to increasing their sizes. I don't want another bag phone.
I get it...everyone has different needs and desires in their life. The OP is right to an extent. Apple created that "wow" factor back in 2007 when the original iPhone came out. Sure, they were "slow" for web browsing and didn't have MMS, but hey, they were tough phones that had amazing technology in them. Now they're creating phones that break if you use them in the course of every day life. Wifi problems, cellular problems, finishing quality problems, hardware component problems (such as sleep buttons not functioning on iPhone 5s).
Apple became incredibly mainstream in recent years. You look around tons of people have iPhones. "i"-Products are taking over lives. You'd be hard pressed to walk into a restaurant, store, bar, business, anywhere really and not find a dozen Apple products (assuming there were enough people in the location) that individuals have with them.
